Replace values

Hello

I am struggling with two things to do with replacing values. 

 

https://www.dropbox.com/s/0j792l4jlkfsigr/Replace%20values.pbix?dl=0

https://www.dropbox.com/s/vvedv43zubsptxh/Replace%20value%20issue.xlsx?dl=0 

 

1. I need to do a conditional replace values. In the linked examples (one pbix file and one excel) i would like to say;

 

If {Q1,Q2,Q3} = "Not at all" then 0 else 1 - but I have no idea how to write this in 'm' language. 

 

2. I have data whereby the response is spelt wrongly or with CAPs in some answers and lowercase in others. Is there a way in m language the below

 

If {Do you agree with this rating?} = "Yes" or "yes" or "y" then 1 else 0

 

I have attached a sample file - I am not very well versed in m language so if you can make the solution user friendly it will be greatly appreciated!

I've replaced the value from "Aptiv" to "Karnataka"

 

But for some reason, I can still see "Aptiv" , similar to these there are many other values didnt change. Not sure why it didnt change.

 

I used Advanced Editor to change, I have provided the below code for your reference.

 

#"Replaced Value82" = Table.ReplaceValue(#"Replaced Value81","Aptiv ","Karnataka",Replacer.ReplaceText,{"State/Province"}),

 

Also another state name "Andhra Pradesh" repeating twice, I have used trimmed and clean columns before replacing the value but still no changes. Can somebody provide some inputs on this please.

 

it should work

in any case you have another option. is to create a dataset with 2 columns, nameold and namenew and then in dax create a new column like finalname that check the newname

In powerBI you can do using the commands automatically.

 

In the query editor window you have the option in tab transform to "replace values". you need to do

- Select the column that you want to analyze
- Click on replace columns
- Write the condition

Maybe you need to do this for each condition that you have. Automatically the powerbi will write this in the M query.

Same for second point

Hi

 

Thanks so much for your advice. I am familiar with the replace values step unfortunately I have to do this for several columns and responses so it would take me quite a while. It would be much more efficent for me to be able to replace one value and use else for all others.

 

Thank you

Brilliant thanks so much!

 

Just a pointer for learners (like me). I had to include [Q3] as [#"Q3"] and [Q2] as [#"Q2"] etc.... for it to work. But it now works like a dream 🙂
